Be itknownzthat I, (Sn-mums Russnnn, a citizen. of the United? States,and resident of Chicago, county of Cook, and: State" of Illinois, haveinvented certain new and useful Improvements Gar-DoorH'angers, of

which the following: is a specification, and

which are illustrated in the accompanying drawings, forming a partthereof. The invention relates to the doors of railway freight cars: andmore particularly" to the means employed for supporting and guiding thedoor in its edgewise movement over-the door opening H The object of theinvention is to provide an improved car door" hanger construction whichshall be efficient in: operation,' em

bodying the use of only inexpensive materials and parts and serve theadditional function of strengtheningthe car door.

In the accompanying drawings,- Figure l is a detail-side elevation ofarailway box car showing the door in open position. Fig. 2 is atransverse vertical sectional View of the same with some of the partsshown in elevation, and"with'other parts broken away. Fig. 3 is a detailsectionalview showing one method which may beemployed for securing thesupporting and strengthening rail upon the door; Fig. tisdetailperspective view showing another form of attaching means employedfor securing the-said rail upon the door, and Fig. 5"is a detaillongitudinal sectional view of an end portion of the rail, a

terminal cap or headthereforbeingshown in elevation.

The side wall of a car is indicated at lO, its door opening beingrepresented at 11. The door 12 has the usual edgewise move: ment overthe side wall 10 of the car and in front of the opening 11'. Outwardmove"- mentof the lower edge of the door is prevented in any convenientmanner as by means of guide brackets, one of which is conventionallyshown at 13.

In carrying out the invention the door 12 is preferably constructed witha horizontal rabbet or recessed portion 14, extending along the upperedge of the door upon the inside. beted portion is provided byconstructing the door 12 in two layers 15, 16, with the inner layer 16terminating below the upper edge of the door. Within the rabbet 14, andagainst the exposed portion of the inside face of the outer layer 15, issecured an S- In the arrangement shown this rabshapecl tracky generallydesignated: t7;- This trackifsf'desirably constructed 'from -a singleP1669036 pipe bent t'o provide threehorizontalin'a-iil sections 18,-1 9,20, each substantially equat in length to thewidth ot the door andwith-=5 the j acent sections connecting near the opposite margins of thedoor, as at 21', Thistrackis firnrly secured in position and serves bothas guiding rail for supportingthedoor in its mi'ovement}and as areinforcementfor stifiimingthe door.

The: means employed for securing the track l 7 in position upon thedoorW-iIl prefer'abl'y be such as to firmly hold it against d-i'slod-gment.As shown, the pipe from which the track is formed-is boredatintervalsthroughout its length to provide apertures 23 for thereception ofattaching screws 24, or bolts 41 and openings 25, in alin'ernent witheach of -thejapertu-res"23, to permitthe insertion of the attachingscrews 24; or bolts 41-,as-also of tools tobeused' in setting the screwsor bolts: Preferably" the screws- 23' are .used at frequent intervalsPawnee-dome 8, iters.-

track 17 and a-boltz fl 'whichpasses-entirely through the outerlayer 15"of the door is used adjacentveach of the-extreme ends of the track. f V

When the door'12 is positionedf for service, the track 17' is engagedwith rollers, as.29, 30,31, 32, 33 and 34:, arranged two sets upontheside wall '10 of the'carL' The rollers of one set, as 29, 30 and 31are located above the level" of'the't'op of the door opening 11 and. arepositioned to be embraced between the upper rail 18 and'intermediaterail 19 of the track 17 in the-closedposition of the'door. The rollersof the' other set, as 32, 33 and 34 are located at one side of the dooropening'l'I and atthe proper level'to be embraced between the lower rail20 and intermediate rail, 19 of the track 17 in the open position of thedoor. Each of the rollers is rotatably mounted upon a bolt, as 85, whichextends throughrthe side wall 10 of the car, and preferably with aspac-.

ing washer 36 located under the roller. For i the purpose of economizingspace, the head, as 37, of each bolt 35, is countersunk in the outerface of the corresponding roller. To

thereon, intermediate its ends for,engage-' ment with the side wall ofthe car through which the bolt is extended.

When the track 17 is constructed from pipe as shown, each of the rollers29, 30, 31, 32, 33 and 34 is formed with a grooved periphery and thegreatest diameter of each roller is slightly in excess of the distancebetween the adjacent rails 18, 19 and 19, 20, of the track. The rollersaccordingly serve both for guideclly supporting the door in itseclgewise movement and for preventing outward displacement of the upperportion of the door. If the rollers of the two sets be positioned forthe engagement of the two outer rollers as 29 and 31 of the upper setwith the upper and intermediate rails 18, 19, of the track 17 adjacenttheir opposite ends, in the closed position of the door, and for theengagement of the outer rollers, as 32, 34 of the lower set with theintermediate and lower rails 19, 20 of the track 17 adjacent theiropposite ends in the open position of the door, the track 17 will alwaysbe engaged with a sufficient number of the rollers to efficientlysupport the door in any position. To facilitate the engagement of therollers with the track in the movement of the door, the opposite ends ofthe track are preferably pointed, as by inserting a pointed plug in eachend of the pipe from which the track is formed. The application of thedoor to the car is permitted if provision is made for securing at leastone of the rollers, as'31, in place upon the side wall 10 of the carafter the positioning of the door. For this purpose the door 12 isformed with an opening 39 in line with the axis of the roller 32 in theopen position of the door through which the bolt 35 upon which theroller 32 is to be mounted and a tool for driving the bolt may beinserted. After the roller 32 has been fixed in position, the opening 39is desirably closed by a plug 40. The track 17 is shown as being coveredby a cleat 11 which is mounted upon the top of the outer layer 15 of thedoor and extends inwardly over the rabbet or the recessed portion 1% ofthe door.

I claim as my invention,

1. In combination, a car wall having a the door opening, and acontinuous track of round cross section secured against the inside faceof the door and folded to provide three rail lengths at diflerentlevels, the lower rail being engageable with the peripheral grooves ofthe rollers of the lower set from below, the upper rail being engageablewith the peripheral grooves of the rollers of the upper set from above,and the intermediate rail being engageable with the peripheral groovesof the rollers of both sets.

2. In combination, a car wall having a door opening therein, two sets ofperipherally grooved rollers mounted on the car wall, the rollers ofeach set being in horizontal alinement and the rollers of one set beinglocated above and extending over the door opening, the rollers of theother set being located at a lower level and at one side of the dooropening, a door movable edgewise over the door opening and beingrabbeted upon the inside along its upper edge, the depth of the rabbetbeing substantially equal to the thickness of the said rollers. and acontinuous track secured against the bottom ofthe rabbetedportion of thedoor and folded to provide three rail lengths at different levels, thelower rail being engageable with the peripheral grooves of the rollersof the lower set from below, the upper rail being engageable with theperipheral grooves of the rollers of the upper set from above, and theintermediate rail being engageable with the peripheral grooves of therollers of both sets;
